New 2023 Washington Emergency Rule Extension, Effective April 14, 2023

January 18, 2023

The Washington State Department of Labor & Industries(L&I) extended anemergency ruleon Dec. 13 to speed plan review for modular buildings, among other structures.

L&I filed the original emergency rule (CR-103E) on Dec. 20, 2021. The recent filing will extend the emergency rule to April 14, 2023.

The extension provides time for the Factory Assembled Structures Program (FAS) to develop permanent rules. The emergency rule allows licensed professional engineers, architects, or firms to review and approve design plans for conversion vendor units, recreational vehicles (RV), and park model RV’s. It also clarifies design plan requirements for commercial coaches and factory-built structures.

FAS plans to file a proposed rulemaking (CR-102) for permanent rules early next year. The changes under consideration include procedures in the emergency rule. These procedures have successfully lessened the backlog to the benefit of customers and staff.

You can find information about this rulemaking here or by going online to the program’s “Laws & Rules” page. For more information about using licensed professionals for design plan review, visit “Modular & Other Mobile Structures” on the FAS website.
